cp-design-system is an open-source UI kit for React and React Native. Write a screen once and it renders natively on the web, iOS, Android and Expo with the same API. 41 accessible components, from buttons and forms to toasts, modals, bottom sheets and carousels, built on Atlassian’s design tokens. Pass one brand color to re-theme everything in light and dark mode. Smooth springs and gestures run on the UI thread, and respect reduced motion. TypeScript, MIT, free on npm.
